Stop Minimizing on Focus Loss

A client-side Minecraft mod that keeps fullscreen Minecraft visible when you alt-tab, click another monitor, or move focus to another application. Version 1.0.0 supports native and borderless fullscreen across a large range of Minecraft and loader versions.

Install the jar that matches both your Minecraft version and mod loader. No server installation is required.

Features

• Prevents supported fullscreen windows from minimizing when focus is lost.
• Lets you enable or disable minimization prevention independently of fullscreen mode.
• Provides native and borderless fullscreen modes.
• Defaults to borderless on Windows and native fullscreen with auto-iconification disabled elsewhere.
• Follows the monitor containing most of the Minecraft window.
• Stores two portable settings in config/stop-minimizing-on-focus-loss.properties.
• Adds a Fullscreen settings entry to Minecraft's main Options screen on supported GUI targets.

Configuration

Open Options → Fullscreen settings in Minecraft. The page controls:

• Fullscreen: Minecraft's normal fullscreen setting. F11 and other screens use the same value.
• Prevent minimizing on focus loss: enables or disables this mod's focus-loss policy.
• Fullscreen mode: chooses native or borderless fullscreen.

The Options entry searches for a free position without moving other mods' controls. On crowded screens it can shrink to ... or hide until a slot becomes available.
